So, for 25G, your training cost 50% less during 30 days and for 53G, it is 90% less : Does it a good thing ? Yes but not for everybody, Let’s see when you need to sign a contract and when it is not a good choice.

Like everybody, you have 4 Training grounds,
- The first one has no cost and it can give you between 5 and 20 strength per use
- The second one costs 0.19G and it can give you between 2.5 and 10 strength per use
- The third one costs 0.89G and it can give you between 5 and 20 strength per use
- The last one costs 1.79G per use and it can give you between 10 and 40 strength per use

Depending the quality of your training grounds, it means that you can gain between 5 (using only the free one at quality 1) and 90 (by using all at quality 4) per day. On the last case, it will cost you 2.87G per day (without Training contract).

Well, now is the time where I will use some maths.

Let’s check for each case :Attention : profits from super soldier medals are ALWAYS considered in these calculus

Case 1You use ONLY the first one :

Your training cost = 0G in 30 days
You gain between 5 and 20 Strength per use, + 1.8 Str via the 5 days bonus (you can gain 9 str if you work and train during 5 days in a row)

It will take you between 11.47 and 36.77 days to gain a Super Soldier medal. Your monthly income will be between 4.08 and 13.08G per month

Because your training cost is equal to 0, you should be insane to buy a training contractCase 2You use the first and the second ones

Whatever its qualities, it will cost you 30 X 0.19G = 5.7G
With the 5 days bonus, you will gain between 9.3 and 31.8 strength per day. You can lose between 0.12G in a month (only with both in quality 1) and gain 13.38G (both in Q4) in a month

So, in any case, you will lose between 8.77and 22.27G with the 50%
And between 34.49 and 47.99G with the 90%

Best choice is : Have max 13.38G as income by signing NO CONTRACTCase 3You use the first, second and the third ones

Whatever its qualities, it will cost you 30 X 1.08G = 32.4G
With the 5 days bonus, you will gain between 14.3 and 51.8 strength per day. You will lose between 1.32 (all in Q4) and 23.82G (all in Q1) in 30 days without any contract

With the 50%, it will cost you 30 X 0.54 = 16.2G and add 25G for the contract. Which means that total cost will be 41.2G. Depending qualities of your training grounds you will lose between 10.12 and 32.62G in 30 days

With the 90%, it will cost you 30 X 0.108G = 0.324G and add 53G for the contract. Which means : total cost = 53.324G. Depending qualities of your training grounds, you will lose 25.16 and 47.66G in 30 days.

Like case 2 : If you use all training grounds (except the last one), you have no interest to buy a training contractCase 4

You use the first, second and last ones

Whatever its qualities, it will cost you 30 X 1.98G = 59.4G
With the 5 days bonus, you will gain between 19.3 and 71.8 strength per day. You will lose between 16.32 (all in Q4) and 47.82G (all in Q1) in 30 days without any contract

With the 50%, it will cost you 30 X 0.99 = 29.7G and add 25G for the contract. Which means that total cost will be 54.7G. Depending qualities of your training grounds you will lose between 11.62 and 43.12G in 30 days

With the 90%, it will cost you 30 X 0.198G = 5.94G and add 53G for the contract. Which means : total cost = 58.94G. Depending qualities of your training grounds, you will lose 15.86 and 47.36G in 30 days.

So, If you use the first, second and last ones : The best choice for you is to sign a 50% contract. You will save 4.7 Gold Case 5You use every training grounds

Whatever its qualities, it will cost you 30 X 2.87G = 86.1G
With the 5 days bonus, you will gain between 24.3 and 91.8 strength per day. You will lose between 31.02 (all in Q4) and 71.52G (all in Q1) in 30 days without any contract

With the 50%, it will cost you 30 X 1.435 = 43.05G and add 25G for the contract. Which means that total cost will be 68.05G. Depending qualities of your training grounds you will lose between 12.97 and 53.47G in 30 days

With the 90%, it will cost you 30 X 0.287G = 8.61G and add 53G for the contract. Which means : total cost = 61.61G. Depending qualities of your training grounds, you will lose 6.53 and 47.03
G in 30 days.

Here, the best choice is to take the 90% one: You will save 24.49G in 30 daysSummary
Well, if you aren’t that good in math, or was annoyed with all of these numbers, I made that part for you

Don’t buy any contract if
- You use only the first one (free)
- You use the first and second ones
- You use the first, second and third ones

Sign a 50% contract only if you use the first, second and last one
Sign a 90% contract only if you use all training grounds

Last thing : before sign a contract, it is better to save your golds to upgrade at least your first and second ones

Everybody note that in cases 3,4,and 5, you LOSE gold no matter what level your training is. So don't use EITHER 3 or 4 training at ANY level, with or without the contract.

It is possible to make a slightly (very slightly) greater income by having training 3 at level 4, but only use it when your strength is within 20 points of the next SS. However it takes a LONG time to recover the cost of upgrading 3 to L4 (I'm talking years)

Not using all your training grounds at level 4 (given it's a very long term investment) means you forfeit decent chances at frequent battle hero medals in division 4. After a bit over a year I can now add an average of 2 medals in division 4 to my monthly income making the overall fight/train combination financially positive.

I expect that the number of medals will go up in the future as the number of EB required to get one continues to go down. You shouldn't neglect the long term side effects of strength. So yes, Years, but that's no difference in the economy module where a Q7 investment takes years to become profitable. It's a choice of carreerpath you need to make.
